acorporatincf'New Yrkl' 1.', Myinvention relates tothe textile machinery artand particularlyto'aldevice for' applying one ormore marks'on yarn vas itis bein? wound 'on` a, Winder of the Abbot orjrevol-ving type for thepurpose of identifying, as allot, the yarn'which is Wound .at the same time' on a'plurality of bobbins carried by the [winden 'While it is the usual practice to mark the yarns on the bobbins asy theyjare rotatingjn'the Winder, this is generally done by holding ajpiece'of Vchalk orja crayon Iagainst the yarn. Y

-One' ofthe voloj'ectsof my vinvention is to provide'a simple, substantially fool-proof device for ,automatically 'marking the yar'n on the -bobbins 'dringfthe winding thereof. Another Objectis to provide a device 'ofthis characterwhich-,Will be automatically controlled to`brin`g lthe marking means into contact with the yarn on the bobbin asthe bobbin passes by the point where the marking device is positioned and, thereafter, t0 raise the marking device so that it will not interfere with the movement of those parts of the Winder, such as the traversing mechanism, which vare disposed between the bobbins. Another object is to provide adeyicefof thischaracter in which the marking means, lsuch as a crayon, will be automatically fed towards the yarn to compensate for wear. A further object is to provide a means cooperating with the yarn andv also with the crayon for limiting the feeding of the crayon vsubstantially to that very short interval during which the crayon is disposed over the yarn.

I accomplish these objects by means of the novel elements and the combinations and arrangements thereof described below and illustrated in the accompanying drawings in which- Fig. l is a fragmentary, plan view of so much Vof a loom lling bobbin Winder as is necessary to illustrate the operation of my invention in connection therewith;

Thus,A it will be,appare`nt-1',hatl unlessythe-downward `movement of the crayons is "restrained in some vway, they will fall, out of the-bottorns of the tubes when not in contactwi-th Lthe--yarr-i-Qn the bobbins. l

In order to contro1the-downwardsliding'movement Aof thejcrayon's in `lthe --tubes l2 and l3,-I have providedva clutch element for -eachcrayon which is normally inY frictional engagement-with the crayon andjholdsit in-xedrelation-tothe tubular element l in which it is held but which is adaptedv automatically' to release -the *crayon when the clutchV mechanismis contacted bythe yarns on thefjbobbins-,-asethey `pass Aunder the Asillustrated inthe drawing,`-each clutch element kcomprises a piece of comparatively stiff wire bent, as shown,l to'provide'two'paraueldisposed portions I3 and l 9 and a rdepending loop portion 2li. Each ofthe portionsl AH is mounted to oscillate ina horizontal bearing 2| on one side of the block I6 near the bottom thereof. The portions I9 which are above the portions I8 are retained within the transversely-extending slot 22 in the block IB by means of the depending portions 23 of the plate 24 which extend at least partially over the entrance to the slot, as shown in Figs. 4, 5 and 7. The portions I9 of the clutch elements can oscillate freely in the slots 22 towards and away from the tubes I2 and I3, and, within the range of movement of the portions I9, each of the tubes is cut away, as perhaps best shown in Figs. 4 and 5, to expose the crayons to contact with the portions I9 of the clutch elements.

Each of the portions I9 is normally held in frictional engagement with the crayon associated therewith by means of a helical, tension spring 25 cooperating therewith. The depending looped portions 20 of the clutch elements extend downwardly below the block I6 and are adapted to contact the yarns on the bobbins as they pass under the marking device, as shown in Figs. 3-6, inclusive.

When the depending looped portions 20 are not in contact with the yarns on the bobbins, the portions I9 of the clutch elements are held in tight, frictional engagement with the crayons by means of the helical springs 25, as shown in Fig, 7. Bearing in mind that the bobbins are moving in the direction of the arrows shown in Figs. 4-7, it will be apparent that when the yarns on the bobbins strike the portions 20, these portions will be swung counterclockwise in the bearings I8, and the portions I9 of the clutch element will also be swung counterclockwise to vthe positions shown in Figs. 4 and 5 and out of frictional engagement with the crayons. Thus, the crayons are free to slide downwardly in the tubes I2 and I3 by gravitational action assisted by the weights I1 superimposed thereon so that wear on the crayons is automatically compensated.

Referring now to Figs. l, 2, 3, 4 and 6, the marking device shown in Figs. 3-7, inclusive, is

supported in operative relation to the bobbins .1.

on the Winder as follows:

The block I6 is attached to an arm 26 by means of screws 21 which cooperate with the threaded holes 28 in block I6. The arm 26 is secured to a shaft 29 which is mounted to oscillate in bearings 30, 3I and 32 in, or secured to, the bar 33 which is supported on the vertical post 34. Also secured to the shaft 29 is the depending lever 35, the lower portion of which is adapted to ride, at times, on the housings 6 (see Figs. 1 and 2). The function of the arm 35 is to maintain the marking device normally raised above the path through which the bobbins on the Winder and the parts of the Winder disposed between the bobbins pass. Thus, when the lower portion of the depending lever 35 is riding on top of the housings 6, the crayons and the depending looped portions of the clutch mechanism are held above and out of contact with the yarns. As illustrated in Figs. 1 and 2, the depending lever 35 has just dropped olf the top of the housing 6 immediately adjacent thereto at the right, at which time a bobbin is positioned immediately below the marking device so that, as the depending lever 35 drops .off said housing to the right, the crayons are brought into contact with the yarn, and the loopedportions 20 of the clutch mechanism, when they contact the yarn, release the crayons so that they are free to move toward the yarn if they are not already in contact therewith. How- Cil ever, as soon as the bobbin which is immediately under the marking device, as illustrated in Figs. 1 and 2, passes to the right, the depending lever 35 rides over the next adjacent housing 6 on the left and raises `the marking device out of the path of those parts of the Winder which are disposed between the bobbins; and, at the same time, the crayons are frictionally engaged by the portions I9 of the clutch mechanism so that they cannot drop out of the tubes I2 and I3.

Since it may be desirable to mark the yarns on the bobbins only when the bobbins are substantially filled, an adjustable stop screw 36 (see Fig. 2) is provided to cooperate with the arm 26 to limit the downward movement of the marking device.

From the foregoing, it will be apparent that, by means of my device, the yarn on each bobbin will have applied thereto, during the winding thereof, one or more circumferential marks which may be in any desirable color or combination of colors so that all of the bobbins which are simultaneously wound will be identified as a lot or group. As the crayons wear, they will be automatically fed towards the bobbins so that such wear will be compensated.

While I have illustrated only two crayons, it is to be understood that either one or more than two crayons may be employed if desired.

While I have described my invention in its preferred embodiment, itis to be understood that the words which I have used are words of description rather than of limitation and that changes, within the purview of the appended claims, may be made without departing from the true scope and spirit of my invention in its broader aspects.

What I claim is:

l. In a bobbin winding device of the type in which a plurality of spaced bobbins having 'their axes substantially horizontal are moved around in a continuous path simultaneously with the winding thereof; the combination with means for holding a crayon in close proximity to the path traversed-by said bobbins, a mounting for said holding means adapting it to move towards and away from said path, whereby to move a crayon held by said means into and out of said path; means cooperating with said holding means for controlling the movements thereof in timed relation to the movements of said bobbins past said holding means to bring said crayon into contact with the windings on said bobbins as they pass said holding means and thereafter to move said crayon out of the zone through which said windings pass, and means cooperating with a crayon when in said holding means and actuated by the windings on said bobbins for effecting a movement of said crayon, relative to said holder, and towards said path to compensate for wear on said crayon.

2.
